When the son is 8, the father is five times that so 8*5 = 40, difference between their ages is 32

An obtuse angle is an angle that is in between 90 degrees and 180 degrees. It looks like this
Answer:
5.14 km
Step-by-step explanation:
A semicircle is 1/2 of a circle so the perimeter is just 1/2 of the circumference
C = 2 * pi r for a circle so for a semicircle
1/2* 2* pi *r
pi*r
3.14 * 1
3.14
If we want to include the piece that closes the semicircle, we need to add the diameter
d = 2r = 2(1) = 2
2+3.14 = 5.14
4x-1=x+26
3x-1=26
3x=27
x=9
